APPARATUS FOR CHANGING BED-SHEETS FOR SICK-BEDS.

SPECIFICATION forming part of Letters Patent No. 614,870, dated November 29, 1898.

Application filed June 18, 1898. Serial No. 683,892 (No model.)

T0 aZZ whom it may concern:

Be it known that I, ALBERT KAEDING, merchant, a subject of the King of Prussia, residing at Halberstadt, Kingdom of Prussia, Empire of Germany, have invented a certain new and useful Apparatus for Exchanging Bed-Sheets of Sick-Beds, of which the following is a specification.

My invention relates to an apparatus for exchanging the bed-sheets of sick-beds. For this purpose the bed -sheet on which the patient lies and which is fastened to cords by means of hooks is drawn up, whereupon a fresh sheet is hooked underneath the old one and the latter drawn away from between the patient and the fresh sheet.

Figure 1 in the accompanying drawings is a partial section of a side view of the mechanism attached 4 to the bedstead, with the sheet to be exchanged partly drawn up. Fig. 2 is an end view of the bedstead provided with the mechanism, at one side seen from the front, the sideboard of the bedstead being out, and the other side being a backward view.

The apparatus consists of four supports a, which by means of the straps b are strapped to the corner-posts of the bedsteads. At the upper ends of the supports a and in the four inner corners of the bedstead-frame ringscrews 0 are provided, through which the guide-poles cl are put. The latter serve as guides for the hooks e, which engage eyelets f in the bed-sheet. ening-seam f, through which a cord is passed for additional strength. From the hooks e ropes g extend up and over pulleys h, journaled in the posts a, said ropes having handles 2'. Hooks 76 are provided on the posts at different heights to engage the ropes.

The apparatus is used in the following manher: The bed-sheet on which the patient is to lie need only have the width of the bedstead and must be provided at the ends with a wide seamj",through which for the sake of strengthening a cord is drawn. At the end of the cord and of the bed-sheet rings (eyelets) f are provided, When the hooks e are hooked This sheet has a strength into the rings f, the bed-sheet is stretched out perfectlytight, thus doing away with the uncomfortable folds. WVhen the patient is to be raised or the bed-sheet to be renewed, the cords g, which are guided over rollers h, are fastened to the rings of the hooks e and the handles '5 at the ends of the cords are pulled. Thus the patient is drawn up or raised with out having to be touched.

If there is only one attendant, the same can, by gradually raising the single corners successively, by himself lift the patient, for which purpose, as shown by Fig. 1, hooks 7a are provided at the supports a. The exchanging of the bed-sheet is then effected in a simple manner by first stretching the new sheet underneath, then unhooking the old sheet and hooking on the new one-that is to say, the old sheet is first unhooked, then the new sheet is hooked on and the old one in the meantime also hooked on again on the top until this has been done at all four corners, then the two corners of the old sheet are unhooked at the head end while those of the new sheet remain in the hooks, then the cord is removed out of the seam of the sheet, whereupon the upper (the 01d) sheet is withdrawn from underneath the body toward the feet, which manipulation can be carried out without the least inconvenience to the patient, because the latter always rests safely on the parts of the new sheet as they become free. Attention must principally be paid to the top part of the old sheet being turned down in order that the body may not have to be in convenienced by the friction.

That I claim as my invention, and desire to secure by Letters Patent, is-- 1. In combination in an apparatus for changing bed-sheets, the sheet the supports Ct, the straps Z) for connecting the same to the bedstead, the guide-poles cl carried by the said supports, the hooks c sliding thereon and adapted to hold the sheets and the cords g for raising and lowering the sheets substautially as described.

2. In combination, the sheet the supports 0 having the rollers h, and hooks 7c, the

guide-poles (Z carried by the supports, the hooks e sliding on the guide-poles and the ropes connected to the hooks passing over the rollers and having the handles 2', substantially as described.

3. In combination with the bedstead, the sheet the guides at the four corners thereof,the fastening devices sliding on the guides and adapted to engage the sheet, and the ropes for raising and lowering the fastening de- 10 vices, substantially as described.

In Witness whereof I have hereunto set my hand in presence of two witnesses.

ALBERT KAEDING.
